CPULD researchers can now predict joint stiffness in wooden pallets manufactured with alternative fasteners

In order to design pallets that can be used safely, the load capacity of the pallet needs to be measured or calculated. Although the load capacity of a pallet depends on a multitude of factors, the stiffness of the joints between pallet components has a major influence on overall pallet load capacity. Heavy-duty pallets are often assembled with alternative fasteners such as bolts and lag screws. Currently, the effect of these alternative fasteners on joint stiffness is not understood; this limits the use of these fasteners by the industry. Therefore, the objective of this research was to investigate the stiffness of pallet joints constructed using alternative fasteners such as bolts and lag screws.
